Multistage Cold Extrusion Process and Forming Rules of Shaft Parts Used in Gearbox

Abstract:

The production method of a driving axles used in gearbox is presented in this paper. A five-stage cold extrusion technology for forming the driving axle was made. First, simulations based on thermal-mechanical coupling finite element model were performed with Deform_2D. During the forming process, the concave appeared at the shaft end. And its formation mechanism was studied. Then the forming rules were obtained. Corresponding experiments were carried out and quality forging was achieved. Simulation and experimental results both indicate that the five-stage cold extrusion technology was feasible.
